New Persian (Persian: فارسی نو, romanized: fārsī-ye now), also known as Modern Persian (فارسی نوین) is the current stage of the Persian language spoken since the 8th to 9th centuries until now in Greater Iran and surroundings. It is conventionally divided into three stages: Early New Persian (8th/9th centuries), Classical Persian (10th–18th centuries), and Contemporary Persian (19th century to present).
Dari is a name given to the New Persian language since the 10th century, widely used in Arabic (see Istakhri, al-Maqdisi and ibn Hawqal) and Persian texts. Since 1964, Dari has been the official name in Afghanistan for the Persian spoken there.
